I have a DVD+RW drive on my laptop that supports 4X burning and can burn 4X DVD+RW Imation disks fine. But lately, 4X disks have become hard to find and only 8X disks are being sold. My drive has the lastest firmware update (Ricoh 1.03 for 8165). I am wondering if i can burn on these disks but at 4X. Any clue if it could work or is it a 50/50 thing? Thanks for any suggestions!
